Tutton

Tutton salts The isomorphous salts M2 SO4, M S04,6H20 where M is an alkali metal and M is a diposilive transition metal. 

Tutton salts are the double sulfates M2Cu(S04)2.6H20 which all contain [Cu(H20)e] + and belong to the more general class of double sulfates of M and M cations which are known as schbnites after the naturally occurring K /Mg compound. 

The rhombic bipyramidal crystals of potassium sulphate form an isomorphous group with those of the corresponding salts of rubidium and csesium. The axial ratios and mol. vol. are indicated in Table XXXVI the axial ratios and topical parame.ters of the three last-named salts were determined by A. E. H. Tutton.26... 

The indices of refraction61 of crystals of potassium, rubidium, and caesium sulphates have been measured by A. E. H. Tuttou, H. Topsoe, and C. Christiansen. A. E. H. Tutton s values at 18°-20° are ... 

M. Erofejeff8 found the refractive indices of ammonium sulphate for lithium and sodium light for vibrations parallel to all three axes and A. E. H. Tutton found for the o, j8, and y indices of refraction, where the vibrations are respectively parallel to the o, b, a axes, at ordinary temp., say 15° ... 

For further information on stereographic projections and the spherical trigonometry necessary for handling goniometric data, books by Miers (1929), Tutton (1922), and Barker (1922) may be consulted.

The most simple oxygen donor is the water molecule, which predominantly functions as a monodentate ligand notwithstanding the presence of two lone pairs on the oxygen atom. In aqueous solution the copper(II) ion is solvated to give the hexaaqua copper(II) ion, which also occurs in the various Tutton salts1270 of Table 79(a) and in [Cu(0H2)6](C104)2.1270 1271 In...
